Gas-Fired Forced-Air Furnace
with Electronic Ignition
INSTALLATION
Before installing the furnace, refer to “Pro
cedures for Gas-Fired Furnaces” (packaged with the
equipment) for information concerning com
bustion, venting, piping, and other standard instal
lation practices. Further reference is made to the
current edition of the American National Standard
Z223.1 National Fuel Gas Code.
Each furnace is shipped from the factory com
pletely assembled with multispeed direct-drive
blower and wired ready for indoor heating installa
tion. All sizes feature a printed-circuit board control
center with easy-to-read low-voltage terminal strip
to ensure proper connections. The control center
also provides easy connections for line-voltage
air cleaners.
CAUTK)?i : Do not iosiaB famace in a corrosive
or contasninated atmospheres Miakesnre that ail
local ordinances for combnstion and oircalating
air supply axe observed.

The design of the upflow gas-fired furnaces is
A.G.A. certified for installation on combustible
flooring in alcoves, basements, closets, or utility
rooms.
For accessory installation details, i.e., automatic
vent damper, humidifier, electronic air cleaner, etc.,
refer to applicable installation literature.
Electrical Connections
LINE VOLTAGE WIRING
IMPORTANT: Before proceeding with the elec
trical connections, make certain that voltage,
frequency, and phase correspond to that specified
on the unit rating plate. Also, check to be sure that
the service provided by the utility is sufficient to
handle the additional load imposed by this equip
ment. Refer to the unit rating plate for equipment
electrical requirements.

CAUTION: Use copper or copper-dad aluiainum conductors only. Use a separate branch
electrical circuit for this furnace. A disconnect
ing means must be located within sight of, and
readily accessible to, the furnace.
See Fig. 2 for wiring diagram showing the proper
field high- and low-voltage wiring. Make all elec
trical connections in accordance with the National
Electrical Code and any local codes or ordinances
that might apply.
WARNING: The unit cabinet m.ust have an
uninterrupted or unbroken electrical ground to
minimize personal injury if an electrical fanlt
should occur. This may consist of electrical
wire or approved conduit when installed in
accordance with e.Kisting electrical codes.
exposed to cold air infiltration, drafts from win
dows, doors, or other openings leading to the out
side, or exposure to air currents from warm or cold
air registers; or to exposure where the natural circu
lation of the air is cut off — such as behind doors,
above or below mantels, shelves, etc.
The thermostat should not be exposed to heat
from nearby fireplaces, radios, televisions, lamps,
or rays from the sun. Nor should the thermostat be
mounted on a wall containing pipes or warm air
ducts, or a flue or vent that could affect its
operation and prevent it from properly controlling
the room temperature. Any hole in the plaster or
panel thru which the wires pass from the
thermostat should be adequately sealed with suit
able material to prevent drafts from affecting the
thermostat.
LOW-VOLTAGE WIRING — Make field lowvoltage connections at the low-voltage terminal
strip. See Fig. 2.
Set the thermostat heat anticipator at the
settings indicated below. If additional controls are
connected in the thermostat circuit, their amp draw
must be added to this setting. Failure to make the
setting will result in improper operation of the
thermostat.
